Note: Term “DEP” means that a rated current is set by the manufacture in accordance
with the customer’s ordering. For more information of ordering, see Appendix:

Selection of CT polarity: For example, Figure 12.6-3 shows how change the
CT polarity on a VCT module (AI#1 = VCT#1). Using the cursor by pressing
keys ▲ and ▼ and pressing key ►, go for required setting items.

Note: This screen is a sample. The number of the CTs are dependent upon the
configuration of VCT modules in each IED.
Selection of residual voltage: A residual voltage is obtained by the
computation in three-phase voltages, but it can be obtain directly from a
